A 32x32 CMOS Photogate active pixel sensor matrix

    Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientificpeer-review


    A CMOS photogate active pixel sensor matrix was implemented. The sensor holds a 32 x 32 pixel matrix and every pixel consists of four transistors. The pixel dimension are 26 x 26 mm with a 50% fill factor. The pixel matrix is read out in sequential or random access mode and the out-put signal is analog. The measured conversion gain was 16 mV/e. The dynamic range was 63 dB @ 1.44 ms integration time. A fixed pattern noise was the dominant noise source especially in high illumination levels, 0.34-3.3% p-p of satu-ration level. The measured input referred noise was 56 electrons when exposure time was 1.44 ms. The dark signal was 330 mV/s at room temperature. The power consumption was 2 mW.
